Subject: [PATCH v2] selftests: exec: make binaries position independent
Date: Tue, 16 Apr 2024 20:28:29 +0500 [thread overview]
Message-ID: <20240416152831.3199999-1-usama.anjum@collabora.com> (raw)
The -static overrides the -pie and binaries aren't position independent
anymore. Use -static-pie instead which would produce a static and
position independent binary. This has been caught by clang's warnings:
clang: warning: argument unused during compilation: '-pie'
[-Wunused-command-line-argument]
Tested with both gcc and clang after this change.
Fixes: 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error")
